About pregnancy Meghan Markle announced in early October.
The Duke and Duchess of Sussex are expected to move into Frogmore Cottage - on the same estate as Frogmore House where they held their wedding reception - in early 2019, Kensington Palace confirmed. The newlyweds, who have a baby on the way, will leave the confines of Kensington Palace when they move from Nottingham Cottage to Frogmore Cottage, a sprawling mansion in Windsor.
The British Prince Harry and his wife Meghan move even before the birth of their first child.
The Duke and Duchess's official office will continue to be based at Kensington Palace.
Many royal watchers had speculated the pair would be moving in next to Prince William and Kate Middleton after the Duke and Duchess of Gloucester moved out of a 21-room apartment in Kensington Palace, but the couple have chose to go for something smaller.
Harry and Meghan, who now live in a small cottage on the grounds of Kensington Palace, always planned to upsize, but it was thought they would occupy another palace unit the size of the one Kate and William live in.
Harry and mother-to-be Meghan have been given Frogmore Cottage by the Queen, and it will become their official residence. The Duke and Duchess of Sussex are now residing in Nottingham Cottage within the Kensington Palace grounds.
The couple have been living at Kensington Palace in London, near Harry's brother, the Duke of Cambridge, and his family since their engagement in 2017.

Prior to this report, a royal source revealed that Prince Harry and Prince William had some tension.
Meg-mania then saw thousands of Aussies turn out to congratulate the couple - with hundreds showering them with baby gifts.
"The truth is there simply isn't enough room at Kensington Palace for them and I know they have been looking at Windsor as a possibility since before the wedding".
